Description

Technical Field

[0001] The invention relates to the technical field of surgical instruments, and in particular to a detachable and washable hydraulic lifting operating table position pillow. Background Art

[0002] The surgical position pillow is a pillow specially designed for use in the operating room and placed on the operating table to support the patient's head and neck. Its main function is to ensure that the patient's head and neck remain in a stable position during surgery, making it easier for doctors to perform surgical operations, while reducing the discomfort and complications caused by the patient maintaining the same position for a long time.

[0003] Existing body position pillows mainly use solid or inflatable pillows with a central bulge and arc-shaped descents at both ends, including a cushioning rising section of the neck and shoulders that naturally raises the patient's neck, a central bulge that supports the neck and cervical curvature, and a cushioning descending section of the pillow for exposing the neck surgical area. This body position pillow can fully expose the surgical field and eliminate the discomfort of the patient maintaining the body position during the operation. However, this body position pillow cannot adjust the angle. If it is directly raised on the patient's neck, the neck will suddenly lean back, resulting in excessive stretching and tension in the head and neck muscles. In severe cases, it will cause venous obstruction and affect the operation.

[0004] Moreover, during the operation, the patient's various body positions and physical conditions may be adjusted according to needs. For example, while raising the height of the patient's upper body, the inclination angle of the head relative to the ground does not change, or while raising the height of the patient's upper body, the angle of the head follows the angle of the patient's upper body and rotates simultaneously; some existing body position pillows cannot meet the multi-functional angle change requirements, which is extremely inconvenient during the operation.

[0005] For this purpose, we provide a detachable and washable hydraulic lifting surgical bed position pillow which can provide limited support for the patient's head, support the neck, and adjust the angle between the pillow body and the bed body in multiple angles and ways.

[0021] When the present invention is used, the device is fixed on the bed. There is no technical limitation on the specific fixing method, as long as the lifting plate is flush with the upper surface of the bed when it is in a horizontal position; a quilt or the like can be laid on the lifting plate and the bed, and a human body lies on the bed with the upper back located at the position of the lifting plate and the head located in a groove provided on the pillow body. The groove on the pillow body can limit the placement position of the human head.

[0022] The elastic cloth is located below the human neck; the elastic cloth can be lifted up by moving the lifting rod one up and down to support the human neck. A lifting hydraulic cylinder one is provided to drive the lifting rod one to move up and down. At the same time, two lifting rods two are provided. The lifting hydraulic cylinder two can be used to drive the lifting rod two to move up and down, thereby increasing the raised area below the neck to achieve a sufficiently wide raised area to support the neck, increase the contact area between the neck and the elastic cloth, and make the support for the human neck more comfortable. At the same time, a telescopic hydraulic cylinder is used to drive the lifting hydraulic cylinder two to rotate, so that the distance between the two lifting rods two and the lifting rod one can be adjusted, and then the size of the raised surface of the elastic cloth can be adjusted.

[0023] A rotatable pillow body is provided, which can rotate relative to the lifting plate to increase the lifting angle of the human head, and the lifting plate can rotate relative to the bed body to adjust the lifting angle of the upper back of the human body; and the pillow body can rotate up and down with the lifting plate, so as to rotate relative to the bed body as the lifting plate rotates.

[0024] When the pillow body needs to rotate relative to the bed body following the lifting plate, a magnet is provided at the lower end of the lifting structure, and an electromagnet is provided at the bottom of the box below the lifting mechanism. By removing the power to the electromagnet, the electromagnet and the magnet are released from adsorption. The technical solution for the electromagnet to adsorb the magnet is a prior art, and no further technical description is given. The corresponding or related technical solutions are not given here. The fixing and releasing of the lifting mechanism and the box body can be realized. By rotating the rotating shaft 1, the moving seat is moved forward, and then the transmission shaft 1, the limit plate, and the transmission shaft 2 are driven to move outward, so that the bevel gear 3 and the bevel gear 4 are meshed with each other, and the bevel gear 5 and the bevel gear 3 are meshed with each other. Then, the transmission shaft 1 is rotated to drive the rotating drum and the lifting plate to rotate, and then the lifting plate and the pillow body are driven to rotate relative to the bed body at the same time. That is, when the rotating drum rotates, the connecting rod 3 is driven to rotate, and then the lifting mechanism is driven to rotate. The lifting mechanism and the lifting plate rotate at the same time, which can ensure that the lifting plate and the pillow body rotate relative to the box body.

[0025] When it is necessary to only rotate the angle between the lifting plate and the box body, a magnet is provided at the lower end of the lifting structure, and an electromagnet is provided at the bottom of the box body below the lifting mechanism. By energizing the electromagnet, the electromagnet and the magnet are adsorbed to ensure that the lifting structure and the box body are fixed and limited. The technical solution for the electromagnet to adsorb the magnet is a prior art and no further technical description is given. The corresponding or related technical solutions are not described here. The fixing and releasing of the lifting mechanism and the box body can be achieved. By rotating the rotating shaft 1, the moving seat moves backward, and then the transmission shaft 1, the limit plate, and the transmission shaft 2 are driven to move backward, so that the bevel gear 2 and the bevel gear 4 are meshed with each other, and the bevel gear 5 is disengaged from the bevel gear 3; then rotating the transmission shaft 1 can drive the lifting plate to rotate, thereby adjusting the angle between the lifting plate and the box body. When the rotating plate rotates, the connection position between the pillow body and the lifting plate moves upward or downward, and the angle of the transverse plate relative to the box body remains unchanged, that is, the telescopic length of the lifting hydraulic cylinder 3 remains unchanged. Therefore, the angle of the transverse plate relative to the box body remains unchanged, thereby ensuring that the angle of the pillow body relative to the box body does not change. The connecting rod 1 moves forward and backward relative to the slide rail, and the lifting mechanism moves up and down when the connecting rod 1 moves up and down; (the lifting mechanism will expand and contract up and down with the action of external force, and the technical description is not repeated for the prior art). That is, when the lifting plate rotates, the angle of the pillow body relative to the box body (the upper surface of the bed body) does not change.

[0026] When the rotation angle of the pillow body relative to the lifting plate needs to be changed separately, the lifting hydraulic cylinder 3 is controlled to extend and retract, thereby driving the transverse plate to rotate, so as to change the angle of the transverse plate relative to the horizontal plane. The transverse plate is parallel to the lower surface of the pillow body, and the connecting rod 1 is parallel to the connecting rod 2. Therefore, when the angle of the transverse plate is adjusted, the angle of the pillow body changes accordingly.

[0027] Beneficial effects: The device can adjust the position of the head and support the position of the human neck. In addition, the expansion surface (width) and the protruding height of the neck support position can be adjusted as needed. In addition, an adjustable lifting plate can be provided to adjust the angle of the upper back relative to the bed body. When the angle of the lifting plate can be adjusted as needed, the pillow body rises as the lifting plate rises and the angle of the pillow body relative to the bed body does not change.

The technical solution of the electromagnet adsorbing the magnet is a prior art, and no technical description is given. The corresponding or related technical solutions are not described here. It can achieve the fixing and releasing of the lifting mechanism 9 and the box body 1. By rotating the rotating shaft 1, the moving seat 19 moves backward, and then drives the transmission shaft 1 218, the limiting plate 25, and the transmission shaft 2 30 to move backward, so that the bevel gear 2 20 and the bevel gear 4 34 are meshed with each other, and the bevel gear 5 21 is disengaged from the bevel gear 3 32; then rotating the transmission shaft 1 218 can drive the lifting plate 5 to rotate, thereby adjusting the angle between the lifting plate 5 and the box body 1. When the rotating plate rotates, the connection position between the pillow body 3 and the lifting plate 5 moves upward or downward, and the angle of the transverse plate 27 relative to the box body 1 remains unchanged, that is, the telescopic length of the lifting hydraulic cylinder 3 26 remains unchanged. Therefore, the angle of the transverse plate 27 relative to the box body 1 remains unchanged, thereby ensuring that the angle of the pillow body 3 relative to the box body 1 does not change, the connecting rod 1 24 moves forward and backward relative to the slide rail 7, and the lifting mechanism 9 moves up and down when the connecting rod 1 24 moves up and down; (the lifting mechanism 9 will stretch up and down with the action of external force, and the prior art will not be described in detail). That is, when the lifting plate 5 rotates, the angle of the pillow body 3 relative to the box body 1 (the upper surface of the bed body) does not change.

[0053] When the rotation angle of the pillow body 3 relative to the lifting plate 5 needs to be changed separately, the lifting hydraulic cylinder 3 26 is controlled to extend and retract, thereby driving the transverse plate 27 to rotate, so as to change the angle of the transverse plate 27 relative to the horizontal plane. The transverse plate 27 is parallel to the lower surface of the pillow body 3, and the connecting rod 1 24 is parallel to the connecting rod 2 28. Therefore, when the angle of the transverse plate 27 is adjusted, the angle of the pillow body 3 changes accordingly.
